| Abstract(in English) | Characteristics of clock recovery circuits are experimentally investigated. Three kinds of circuits, phase lock loop (PLL) circuit, injection locking circuit, and circuit composed of a T-Flip-Flop are constructed. As for 80-Gbit/s the input optical signal is down-converted into 40 Gbit/s by an optical modulator droved by the output of the injection locking circuit. Locking frequency ranges, frequency responses, and phase noises are measured and compared among the circuits. The characteristics of the PLL and the injection locking are relatively similar and the T-Flip-Flop circuit shows superior properties except for small dynamic range of input optical power. |
